A construction company completes two projects. The first project has $3,000 in labor expenses for 60 hours worked, while the second project has $2,100 in labor expenses for 42 hours worked. The relationship between the company’s labor expenses and hours worked is linear. Which of the following would correctly calculate the y-intercept of the linear equation? Select all that apply.3,000 = 50(60) + b3,000 = 0.02(60) + b60 = 50(3,000) + b2,100 = 0.02(42) + b2,100 = 50(42) + b42 = 50(2,100) + b
